Specification of Letters Patent. Patented Aug. 13, 1918- Applicationfiled August 21, 1915. Serial No. 46,628.

To all whom it may concern:

Be it known that I, CLYDE J. COLEMAN, a citizen of the UnitedStates,7and a resident of New Rochelle, county of Westchestei, and Stateof New York, have invented certain new and 'useful Improvements inCombined Kinetoscopic and Phonographic Apparatus, of. which thefollowing is a specification.

My invention relates to means for causing the operation of one machineto bear a certain relation to that of another machine, and especially tomeans for operating kinetoscopic machines'in' exact synchronism withAnother object is to provide meansoperated by one device for controllingthe rate of operation of. another device. This object is preferablyattained by providing an escapement for one mechanism controlled by thedriving element of another, each mechanism having a separate source ofpower.

Another object is to provide a continuing source of power for theoperation of one device but to regulate the application of the power tothat device so that it operates in synchronism with 'asecond device.This object is preferably attained by providing an energy-storingmechanism for accumulating power to drive one device and providing .anescapement mechanism to control the applicationof the powerto thatdevice,

the operation of the escapement mechanism being governed by theoperation of another device.

X Other. and further objects and advantages will appear from thefollowing description taken in connection with the accompanying drawingsforming a part of this specification and will be pointed out in theclaims. In the drawings, in which like reference characters indicatelike parts,

Figure 1 is a diagrammatic view of a sound-reproducing machine and akinetoscopic picture-pro'ecting machine connected together by a preerred form of mechanism embodying my invention, said mechanism I beingdesigned to produce synchronous operation of the two machines;

Fig. 2 is a detail. view of the escapement mechanism shown in Fig.1; andj Fig. 3 is a detail view of the commutator or contact-making membershown in Fig. 1. When kinetoscopic pictures are projected upon a screenit is desirable to reproduce all of the' sounds which would ordinarilyoccur when the scene portrayed by the pictures is originally acted.Ordinarily the projecting machine is in front of the screen and thesound-reproducing machine is behind it, and my invention is disclosed inconnection with the ordinary arrangement. The sound-reproducing machine1 is placed behind the screen 2 and the sound passes through theopenings 3 in the screen above the point upon which the images areordinarily projected. An electric motor 4 drives the worm wheel 5 whichisconnected to the phonograph-operating shaft 6. Upon this shaft 6 is abevel gear 7 which cooperates with a similar bevel gear 8 which isdirectly connected to and rotates the record-carrying disk 9' of themachine. *The ordinary sound box 10 is provided and the vibrationsproduced thereby. are amplified by the ordinary horn ll. On the shaft 6is mounted a commutator or contact maker 12. This commutator has asleeve of electricity-conducting material 13- and upon this sleeve isformed a disk 14 of insulating material, which carries in its peripherycontacts 15 of conducting material. These con-- .upon the periphery ofthe disk 14 rests a brush 18 which is connected to the other wire of thecircuit and which makes contact with the contact pieces 15 when theshaft 6 rotates. The circuit referred to is therefore intermittentlymade and broken as the honograph operating mechanism rotates.

he picture projecting machine 20 is positioned in front of the screenand has an operating shaft .21. Connected to this operating shaft isanfescapement wheel 22. A detent or looking lever 23 is pivoted on theframe of the projecting machine at 24 and has teeth 25 and 26 which areoffset from one another in a vertical plane and which alternatelycooperate with the teeth of the escapement wheel as the lever is swungin a horizontal plane about the point 24. A spring 27 holds the detentmember in position to maintain the tooth thereof in engagement with oneof the teeth of the escapement wheel. On the opposite side of the detentmember from the spring 27 is positioned an electromagnet 28 which is inx the circuit A heretofore referred to. It will be seen that each timethe circuit B is enerjournaled a shaft 29 which may be rotated by acrank 30, or which may be rotated by a worm wheel 31 driven by a worm 32on the shaft of the motor 33. The worm wheel 31 is loosely mounted onthe shaft 29. The clutch member 36 is loosely mounted on the shaft 29and is attached to the wheel 31 in such manner that the wheel 31 and theclutch member 36 must rotate together, while the clutch member 36 ismovable longitudinally. along the shaft 29. Normally the clutch member36 is held in engagement with the clutch member 36' by the spring 35.The clutch member 36 is keyed to the shaft 29. men it is desired tooperate the picture machine by hand the nut 34 is rotated to relieve thetension of the spring 35, which spring,then ceases to hold the clutchmember 36 in engagement with the clutch member 36. Mounted upon theshaft 29 is a fly-wheel 37 to which is secured one I end of a spring38'which is coiled about the shaft 29 and has its other end secured tothe escapement wheel 22. It will now be seen that when the shaft 29 isrotated either by the crank 30 or the motor 33, a tension is placed uponsprin 38 and energy is "stored in it which ten s to rotate with theescapement wheel 22. When the phonograph operates, the commutator 12rotates and intermittently makes and breaks the circuit B, therebyintermittently energizing the magnet 28 which causes the detent tooscillate upon its pivot 24, thereby permitting theintermittent'rotation of the escapement wheel 22 and a like intermittentoperation of the projecting machine 20.

The c1rcu1t A provides energy through the switch a to the circuit Awhich operates the motor 4, and to the circuit A" which operates themotor 33. The circuit B receives its power throughthe switch I) fromthe-source BB. In order that too reat a tension may not be put upon thesprmg 38,

a lug 39 is provided upon the escapement wheel 22 which is in the pathof a lug 40 placed upon the fly-wheel 37. It will be seen, therefore,that the fly-wheel may r0-' tate relatively to the escapement Wheel onlyhalf of one revolution from the position shown in the drawing.

While I have described specifically and with considerable detailmechanism whereby a picture-projecting machine is operated insynchronism with a sound-reproducing machine and in which thepicture-projecting machine-operating mechanism may not be operated morerapidly than the operation of the sound-reproducingmachine will permit,I do not intend that my invention shall be limited to the detailsdescribed, or that it shall be limited to the kinds of machines inconnection with whichit is deprovements in combined kinetoscopic andphonographic apparatus, Serial Number 46,629, filed August 21, 1915.Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is I 1.
